摘要： A breast pump includes a body including a hood attachment portion, a bottle attachment portion, and an inner passage extending between the hood attachment portion and the bottle attachment portion; a diaphragm configured to generate negative pressure in the inner passage; a handle manually operated to move back and forth; and a link mechanism configured to support the handle in a manner movable back and forth relative to the body. The handle is configured to change pressure of the inner passage from a normal state to a negative state by displacing the diaphragm in a lifting direction. The link mechanism is configured to apply an operation force to the handle that becomes maximal during handle movement when the handle is moved in an operation direction that changes the pressure from the normal state to the negative state.

摘要： A breast pump includes a main body and a handle. The main body includes an internal passage, a negative pressure generation mechanism configured to generate negative pressure in the internal passage for pumping milk, a hood attaching portion to which a hood fitted to a breast is attached, the hood attaching portion being disposed at a front part of the main body, and a bottle attaching portion to which a bottle for collecting milk is attached, the bottle attaching portion being disposed at a lower part of the main body. The handle is pivotal to the main body and includes a basal end, at a side located closer to a pivot point on the main body, connected to the negative pressure generation mechanism. The handle includes a finger rest at a distal side and extends forward from the pivot point beside the main body.

摘要： [Problem]
To provide a check-valve in which the occurrence of damage such as tearing, deformation, etc., can be suppressed.
[Solution]
A check-valve opens and closes an opening provided in a main body and prevents a backflow of a fluid passing through the opening; and the check-valve includes a base part 71 which is flexible, and a valve part 72 which opens and closes the opening, has a thickness thinner than a thickness of the base part 71, and is connected to the base part 71 in a state in which a periphery of the valve part 72 is surrounded with the base part 71. The valve part 72 seals the opening in a normal state of the valve part 72 being pre-urged toward the main body by an elasticity of the base part 71, and opens the opening when the fluid passes through the opening in one direction.

摘要： The invention provides a breast pump capable of effectively preventing the occurrence of leaking of breast milk from a milk expressing section having an enlarged diameter during expression of milk, and also effectively preventing the loss of negative pressure due to leaking. A breast pump has an accommodating vessel for collecting breast milk; a breast pump main body which generates negative pressure for expressing milk; an enlarged-diameter milk expressing section having an enlarged diameter for abutting against a breast of a user; and a shock absorbing section, at least a portion of which abuts against a breast of a user by being formed in a substantially circular trumpet shape following an opening section of the enlarged-diameter milk expressing section, wherein the shock absorbing section includes an abutting section which abuts against an areola of the user and a tight contact section which makes tight contact with the user's breast.

摘要： An electric breast pump 1 includes a breast placement part 12 at which a breast part including a breast and a nipple of a subject is placed and suction-pressure generating units 10 and 50 that generate a suction pressure in the breast placement part. The suction-pressure generating unit generates a suction cycle including a plurality of different suction pressures. The suction cycle includes basic suction, increased suction with an increased suction pressure, and reduced suction with a reduced suction pressure. A suction pressure difference between a suction pressure increasing in the increased suction and a suction pressure reducing in the reduced suction is an equal pressure and is a pressure difference at a borderline at which a user perceives a change of a suction pressure. In the suction cycle, the basic suction, the increased suction, and the reduced suction are each repeated multiple times consecutively at an equal suction pressure.
